    Do I just pull them out and push them back in or what?

    For preamp tubes, yeah, mostly.
    Make sure to buy paired tubes if needed for your preamp.
    Some preamps require a bias setting, but it's usually only necessary for tube power amps.

    I would take it to the dealer to have it repaired so you wouldn't mess it up!
  4. Unplug the amp, and wait until they are cool (of course). Use a gentle circular motion when removing preamp tubes, this is also the same for power tubes. The proper location of the tube in the socket is insured by a gap in the pin sequence.
  5. I've heard something about gloves so that you don't get hand oils on the tubes. This probably doesn't matter, but it can't hurt.

    Iv'e heard this to, and as far as taking it to a pro, it's not REALLY needed unless it's in a tricky place to get to, and would take removing some parts to get to. just pop em out, pop em in. make sure they are the same, of course. should be something on the tube that says.
